Multi-mode imaging system

摘要

A multi-mode imaging system provides the capability of reproducing documents in a conventional COPY mode wherein a document is placed on a platen and scanned to create an exposed latent image on a photosensitive member. The system is adapted to operate in a second, print (WRITE) mode wherein an image bar, such as a light-emitting diode (LED) array or a liquid crystal shutter (LCS), is placed into optical alignment with a fixed optical system including a linear lens array. The image bar is electrically addressed to create a light output in an image-wise pattern (LCD) or to change the state of the LCS. The image output is optically coupled into the lens array which projects the image onto the photosensitive member. In one embodiment, the image bar is partially within the end portion of a movable plate.
